Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a track box connection self-locking structure and track box. Background Technology

[0002] Track lights are widely used in commercial lighting, industrial lighting and home decoration due to their flexible installation and adjustable lighting angle. The core of the track light consists of the light body, the track and the track box that connects the two. The connection stability of the track box directly determines the safety and reliability of the track light.

[0003] In existing track box and track connection structures, most rely on manual operation for locking. Typical examples include the technical solutions disclosed in CN221743970U ("Anti-detachment track box for track lights") and CN223375709U ("A multi-functional track box"). When installing these track boxes, the box must first be inserted into the preset position on the track, and then additional operations such as manually tightening the locking mechanism and moving the latches are performed to lock the track box to the track.

[0004] However, the aforementioned manual self-locking structure has several technical drawbacks: First, the installation process is cumbersome, requiring step-by-step insertion and manual locking operations, which not only increases the difficulty of installation but also reduces construction efficiency; second, the reliability of locking depends on the standardization of manual operation. If manual locking is not in place, the connection between the track box and the track may become loose, and after long-term use or exposure to vibration, there may be a risk of detachment, threatening the safety of personnel and objects below; third, for structures that partially rely on magnetic assisted locking, the magnetism gradually weakens over time, leading to a continuous decrease in the fixing effect and further exacerbating the risk of detachment.

[0005] In response to the above problems, the applicant proposed a solution. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model is a self-locking structure for connecting track boxes, such as... Figures 1 to 6 As shown, including The track box housing is defined as having a length extension direction that is axial, and a horizontal direction perpendicular to the axial direction that is radial. The unlocking press part 30 is located at the top inside the track box housing, and its top part protrudes through the track box housing and is used to receive the pressing operation. The locking frame 40 is a U-shaped frame with an opening facing downwards. It is located in the upper part of the track box housing. The locking frame 40 is integrated with the unlocking pressing part 30. The bottom of both sides of the locking frame 40 are respectively provided with snap-fit ​​parts 41. The self-locking trigger assembly includes a track abutment portion 50 and a locking tongue plate 60 integrally connected to the track abutment portion 50. The track abutment portion 50 is disposed at the bottom inside the track box housing, and the bottom part of the track abutment portion 50 passes through the track box housing and protrudes to the outside of the track box housing. The locking tongue plate 60 is provided with locking pins 61 on both sides that are adapted to the locking portion 41 of the locking frame 40. The elastic abutment baffle 70 is a horizontal plate structure that can move within the locking frame 40 in the radial direction; The self-locking trigger component is elastically connected to the elastic abutment baffle 70 to form a lower elastic abutment structure, and the unlocking pressing part 30 is elastically connected to the elastic abutment baffle 70 to form an upper elastic abutment structure. The elastic abutment baffle 70 has a travel limit, which is used to limit the radial downward travel of the elastic abutment baffle 70, and in fact, it limits the elastic downward travel of the unlocking pressing part 30 and the locking frame 40. The track box housing has an unlocked state and a self-locking state: When in the self-locking state, the track abutment part 50 is subjected to force and moves radially upward, offsetting the elastic force of the lower elastic abutment structure and the upper elastic abutment structure. The locking tongue plate 60 moves upward synchronously with the track abutment part 50 until the locking pins 61 on both sides of the locking tongue plate 60 engage with the locking part 41 of the locking frame 40 to lock. When in the unlocked state, the unlocking pressing part 30 is subjected to force and moves radially downward. The locking frame 40 moves downward synchronously with the unlocking pressing part 30. The elastic force of the upper elastic abutment structure cancels the elastic force of the lower elastic abutment structure until the locking part 41 of the locking frame 40 disengages from the locking pins 61 on both sides of the locking tongue plate 60.

[0022] This utility model also provides a track box 20, such as Figure 1 , 2 As shown in 3, 4, 5, and 6, a self-locking structure for connecting a track box is included; the track box housing includes a main frame 21 and side cover plates 22.

[0023] This track box 20 is used in conjunction with track 10, such as Figure 1 , 2 As shown in Figure 3.

[0024] After the track box 20 is installed onto the track 10, the track abutment part 50 abuts against the plane of the track 10 and moves radially upward under the action of the plane of the track 10. At the same time, it drives the locking tongue plate 60 integrated with it to move upward as well. Since the unlocking pressing part 30 and the self-locking trigger component are elastically connected to the elastic abutment baffle 70 in the upper and lower directions respectively, during the upward movement, the locking tongue plate 60 counteracts the elastic force of the lower elastic abutment structure and the upper elastic abutment structure until the locking pins 61 on both sides of the locking tongue plate 60 engage with the locking parts 41 at the bottom of both sides of the locking frame 40 to lock. This achieves automatic locking of the track box 20. Figure 3 The left side shows the unlocked status.

[0025] In this invention, the track box 20 can be automatically locked within the track 10 without the need for manual operation.

[0026] When unlocking is required, manually press the unlocking press 30 downwards. The unlocking press 30 moves downwards under pressure, and the locking frame 40, which is integrally connected to it, also moves downwards synchronously. At this time, the downward pressure and the elastic force of the upper elastic abutment structure act on the elastic abutment baffle 70, counteracting the elastic force of the lower elastic abutment structure, until the locking parts 41 at the bottom of both sides of the locking frame 40 disengage from the locking pins 61 on both sides of the latch plate 60. This unlocks the track box 20. Figure 3 The right side shows the unlocked status.

[0027] This invention establishes a self-locking linkage and an unlocking linkage through the unlocking pressing part 30, the self-locking trigger component, the elastic abutment baffle 70, the locking frame 40, and the elastic linkage between the above components. This achieves automatic locking of the track box 20 after it is installed on the track 10, eliminating the need for manual locking. This greatly simplifies the installation process, improves construction efficiency, and ensures the stability of the connection between the track box 20 and the track 10, avoiding the risks caused by human error. At the same time, the unlocking process only requires manually pressing the unlocking pressing part 30 to achieve disengagement, making the operation convenient and efficient and reducing the difficulty of subsequent maintenance.

[0028] Furthermore, in some embodiments of this utility model application, such as Figure 1 , 2 As shown in Figures 3 and 6, the system also includes an elastic drive assembly, which includes an unlocking reset spring 80 and a self-locking drive spring 90. The unlocking pressing part 30 is elastically connected to the elastic abutment baffle 70 through the unlocking reset spring 80, and the track abutment part 50 is elastically connected to the elastic abutment baffle 70 through the self-locking drive spring 90.

[0029] To facilitate the installation of the unlocking reset spring 80 and the self-locking drive spring 90, further, in some embodiments of this utility model application, such as Figure 2 , 3 As shown in Figure 6, spring sleeve protrusions 71 are respectively provided on the upper and lower end faces of the elastic abutment baffle 70. The ends of the unlocking reset spring 80 and the self-locking drive spring 90 are respectively sleeved on the spring sleeve protrusions 71. The unlocking pressing part 30 and the track abutment part 50 are provided with a sleeve inner cavity 72. The ends of the unlocking reset spring 80 and the self-locking drive spring 90 are respectively sleeved in the sleeve inner cavity 72.

[0030] When the track box 20 is not fitted into the track 10, the end of the self-locking drive spring 90 is not in contact with the elastic abutment baffle 70; the two are only physically connected, and the self-locking drive spring 90 is still in a fully extended state. During self-locking, the self-locking drive spring 90 moves radially upward under the drive of the track abutment part 50 and eventually abuts against the elastic abutment baffle 70. The elastic force of the self-locking drive spring 90 then acts on the elastic abutment baffle 70. The self-locking drive spring 90 needs to push the elastic abutment baffle 70 upward to counteract its elastic force, allowing the locking tongue plate 60 to move upward with the track abutment part 50 until the locking pins 61 on both sides of the locking tongue plate 60 engage with the locking parts 41 at the bottom of both sides of the locking frame 40. To smoothly counteract the elastic force of the self-locking drive spring 90, in some embodiments of this utility model application, the elastic coefficient of the unlocking reset spring 80 is smaller than that of the self-locking drive spring 90.

[0031] Furthermore, in some embodiments of this utility model application, such as Figure 2 , 3 As shown in Figure 6, the latching part 41 is a protruding hook that protrudes from the bottom side of the locking frame 40 toward the central axis of the locking frame 40. In order to enable the locking pin 61 of the locking tongue plate 60 to smoothly slide into the protruding hook when locking and to smoothly slide out of the protruding hook when unlocking, the protruding hook is provided with a sliding in slope and a sliding out slope on its bottom surface and top surface, respectively.

[0032] Furthermore, in some embodiments of this utility model application, such as Figure 2 , 3 As shown in Figure 6, the locking tongue plate 60 is provided with a pushing rib 51 on one end face facing the elastic abutment baffle 70. When self-locking, the self-locking drive spring 90 pushes the elastic abutment baffle 70 upward, and the pushing rib 51 also pushes the elastic abutment baffle 70 upward. The soft connection of the self-locking drive spring 90 is changed to the hard connection of the pushing rib 51.

[0033] Furthermore, in some embodiments of this utility model application, such as Figure 2 , 3As shown in Figure 6, travel limit blocks 100 are provided on both sides of the elastic abutment baffle 70. The travel limit blocks 100 are protrusions adapted to the inner wall of the track box housing. The travel limit blocks 100 are used to limit the radial downward movement of the elastic abutment baffle 70. In fact, they limit the elastic downward movement of the unlocking pressing part 30 and the locking frame 40 to prevent the unlocking pressing part 30 from pressing down too much during unlocking and completely entering the track box housing.
